Juniper EX 2200 48T – switch
EX2200 Switches Hardware Overview
Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the enterprise market, including branch offices, campus locations, and data centers. The switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks M Series, MX Series, and T Series routers and SRX Series Services Gateways.
Juniper Networks EX2200 Ethernet Switches provide connectivity for low-density environments.
Benefits of the EX2200 Switch
Support for Virtual Chassis—EX2200 switches support Virtual Chassis technology. You can interconnect up to four EX2200 switches to form a Virtual Chassis and manage and operate them as a single network entity.
High flexibility—EX2200 switches provide a flexible solution that supports converged data, voice, and video environments. EX2200 switches provide 15.4 watts of Class 3 PoE to VoIP telephones, closed-circuit security cameras, wireless access points, and other IP-enabled devices.
Economical—EX2200 switches offer an economical, entry-level, stand-alone solution for access layer deployments in branch and remote offices, as well as campus networks.
EX2200 Switches First View
EX2200 switches are available in models with 12 , 24, or 48 built-in network ports. The compact, fanless model, EX2200-C switches have 12 network ports.
EX2200 switches provide:
-
Up to four uplink ports
-
12 (compact, fanless model), 24, or 48 built-in network ports with 10/100/1000BASE-T Gigabit Ethernet connectors
-
Virtual Chassis capability—Starting with Junos OS Release 12.2, you can connect up to four EX2200 switches (including EX2200-C switches) together to form one unit that you manage as a single chassis, called a Virtual Chassis. For information about understanding and configuring Virtual Chassis, see Virtual Chassis Feature Guide for EX2200, EX3300, EX4200, EX4500 and EX4550 Switches.
-
Power over Ethernet (PoE or PoE+) on all network ports (in PoE-capable models)
Uplink Ports
Each EX2200 switch except the EX2200-C switch model has four uplink ports that support 1-gigabit small form-factor pluggable (SFP) transceivers for use with fiber connections and copper connections.
Each EX2200-C switch has two dual-purpose uplink ports. Each dual uplink port consists of an RJ-45 port (in which you can connect a copper Ethernet cable) and an SFP port (into which you can plug a transceiver). Only one of the ports can be active at a time. By default, if you connect a copper Ethernet cable to the RJ-45 port, this port becomes the active port provided that there is no connection made on the other port. If you plug a transceiver into the SFP port, this port becomes the active port whether or not a copper Ethernet cable is connected to the other port. You can change this default behavior by explicitly configuring a media type—copper or fiber—for the dual-purpose port by using the media-type command. For more information, see Configuring the Media Type on Dual-Purpose Uplink Ports .
You can use an SFP uplink port connection between EX2200 switches to interconnect the switches into an EX2200 Virtual Chassis. For this, you must explicitly configure an SFP port each on the switches to be connected as a VCP. See Setting an Uplink Port on an EX Series or QFX Series Switch as a Virtual Chassis Port.
For information about the supported optical and copper interfaces, see Pluggable Transceivers Supported on EX2200 Switches.
Console Port
Each EX2200 switch except the EX2200-C switch model has an RJ-45 console port that accepts a cable with RJ-45 connector.
The EX2200-C switch has two console ports: an RJ-45 port and a Mini-USB Type-B port. The RJ-45 console port accepts a cable with an RJ-45 connector and the Mini-USB Type-B console port accepts a Mini-B plug (5-pin) connector to connect to the console management device. The switch activates only one console port at a time, either the RJ-45 console port or the Mini USB type-B console port. By default, the RJ-45 port is the active console port and the Mini-USB Type-B port is the passive console port. You can change the default setting of a console port by using the port-type command. See Configuring the Console Port Type (CLI Procedure).

Cable Guard
On an EX2200-C switch model, you can install a cable guard to secure the cables connected to the switch. The cable guard has slots in the front of it through which you can pass all the cables to prevent them from being accidently unplugged or removed after they are connected. See Mounting an EX2200 Switch on a Desk or Other Level Surface.
Security Slots
Each EX2200-C switch model has security slots on the left and right panels of the chassis. Use the security slots to lock and secure the chassis in the installation site with a standard cable lock . See Mounting an EX2200 Switch on a Desk or Other Level Surface.
Power over Ethernet (PoE) Ports
EX2200 switches are available in models with or without PoE/PoE+ capability. Models that support PoE/PoE+ provide that support on all network ports. PoE ports provide electrical current to devices—such as IP phones, wireless access points, and security cameras—through network cables, thus eliminating the need for separate power cords for those devices.
EX2200 switches with DC power supply do not provide PoE.
